The kinetics of oxidation of cyclohexanol by Quin aldinium Fluorochromate (QnFC) has been studied in aqueous acetic acid medium. Cyclohexanol was converted to the corresponding cyclohexanone. The order of the reactions has been found to be one with respect to oxidant an d fractional with respect to the substrate as well as hydrogen ion concentration. Increase in the percentage of acetic acid increases the rate of reaction. The reaction follows Michaelis-Menten type of reaction in a non free rad ical path way. Thermodynamic parameters has been calculated using Eyring’s equation at four different temperat ures. A suitable mechanism consistent with the obse rved kinetics has been proposed.
